GUN.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed May 23,1905. Serial No. 261,782.

T at whom, it may concern.-

Be it known that I, IsIDoRE A. TOMASINI, a citizen of the United States, and a resident of Guadaloupe, in the county of Santa Barbara and State of California, have invented certain new and useful Improvements in Guns, of which the following is a specification.

My invention is an improvement in guns; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings, forming a part hereof, Figure 1 is a side view of a gun provided with my invention with part of the barrels broken away. Fig. 2 is a plan view thereof. Fig. 3 is a longitudinal section through the lock-frame, showing the gun closed, Fig. 4 is a similar view with the gun broken. Fig. 5 is a longitudinal vertical section through the gun. Fig. 6 is a similar view with the gun broken and the hammer set. Fig. 7 is a bottom view of the frame with the covering-plate removed. Fig. 8 is a perspective view of the hammers and sears removed. Fig. 9 is a detail of the sear and hammer engagement.

In the present embodiment of my invention I have shown the same applied to a doublebarreled shotgun of the breech-loading type comprising a stock A and a barrel B, connected by the lock-frame mechanism C.

The frame C of the gun may be of the ordinary construction used in guns of the hammerless type. The hammers 1 and 2 are of the general shape shown in Fig. 8, provided with a firing-pin 3, and are pivoted in the frame by means of the screws 4 through the sides of the frame. The part of the hammer below the pivot is grooved longitudinally to receive the end of a plunger 5, which passes forward into a chamber 6, hollowed out of the frame and normally pushed outward by resilient means 7 On the depending portion of the hammer opposite to the plunger is a gain 8, adapted when the trigger is set to engage the forwardly-extending arm 9 of the sear 10, pivoted in the lower rear corner of the frame and having a rearwardly-extending arm 23 for a purpose hereinafter set forth. The inner side of the depending part of the hammer is formed into a rearwardly-extending arm 12, having a squared shoulder for engaging an upwardly extending lug 13 on the sliding plate 14. The sliding plate is grooved on its lower surface and at its forward end has a rectangular opening 15 for engaging one of the arms of a rock-arm 16, pivoted near the center of the frame, and supports at its rear end a spring-pressed pin 17 in a socket 18, resting in an opening 19 in the center of the frame. It will be understood that the sliding plate is provided with a second lug for engaging the arm of the opposite hammer. The other end of the rock-arm 16 is formed into a yoke 20 and the arms of the yoke are provided with alined perforations to receive a cross-pin 21, adapted to be engaged by the hook 22, pivoted in the lug 23, secured between the barrels of the gun in the ordinary manner.

When the gun is broken, the act of breaking turns the rock-arm 16 upon its axis, pulls the sliding plate forwardly, and by its engagement with the rearwardly-extending arms on the hammers turns them on their pivots until the gain engages the forwardly-extending arm of the scars, thus setting the hammers.

The rearwardly-extending arm 23 of the left-hand sear is provided with an inward extension 21, overlapping an inward extension 25 on the rearWardly-extending arm 26 of the right-hand sear. Covering the opening 27 in the bottom of the frame is a plate 28, having a rearwardly-extending portion 29. A front trigger 30 passes through aslot 31 in the plate and is pivoted in a lug 32 on the upper surface thereof. The trigger is of the general outline shown in Fig. 8 and is held normally depressed by the spring 32, secured to the upper surface of the plate and engaging the rearward face of the trigger. When the depending portion of the trigger is turned rearwardly, its upper surface engages first the inward. extension of the right-hand sear, letting off the right barrel, and further rearward movement causes a further elevation of the extension, which, engaging the inward extension of the left-hand sear, lets off the left-hand barrel.

A barrel lock or bolt 33 passes through'a longitudinal opening 34 in the center of the frame between the triggers and is normally retained in its forward position by a spring 51. A tail 36, pivoted in a mortise 37. in the rear end of the plunger, is provided with an antifriction-roller in its lower end, engaged by a forwardly-extending lug 38 on the rear trigger 39. The rear trigger is pivoted in a lug on the upper surface of the plate and is retained normally depressed by a spring 32, secured to the plate and engaging a notch in the rear edge of the trigger. The forwardlyprojecting end of the plunger 33 engages in the notch 41 on the lug 23, thus securing the barrels and frame in their alined position. When the rear trigger is pulled, the lug 38 is turned forwardly and downwardly and engages the tail of the plunger, rocking the same on its engagement with the mortise and pulling the plunger rearwardly and disengaging it from the notch 12 of the lug 13, allowing the gun to break. The action of the lug is to push the lower end of the tail forward, the upper end of the tail as a consequence pulling the plunger rearwardly. A spring 51, arranged in an opening in the frame, engages a notch in the plunger to normally retain the plunger in its forward position, and a screw 52 closes the outer end of the opening.

A safety-slide 42, having a depending lug 43 in a groove 44 on the rearwardly-extending portion 45 of the frame, is provided for preventing premature discharge of the gun. A sliding plate 46, having an opening to engage the lug 43 and secured thereto in any suitable manner, engages the upper end of a rock-lever 47 ,pivoted in the stock of the gun and provided with an extension 48 for engaging the rearwardly-extending arms of the sears to prevent their elevation by the trigger. By slipping the slide .42 forward and backward the lever is rocked, thus permitting or preventing movement of the sears, as desired.

In operation when the rear trigger is pulled the plunger is withdrawn from the notch in the lug, allowing the gun to break. The breaking of the gun turns the rocking lever and pulls the sliding plate forward, thus cocking the hammer. The gun-barrels are then returned to their proper position with respect to the frame and the gun is ready for action.

It will be evident from the description that a gun provided with my improvement may be fired much quicker than the ordinary two-' triggered gun and that the rear trigger forms a simple yet efficient locking means for holding the barrels and the frame in alinement.

I do not limit the application of my improvement to a double-barreled gun, since it is evident that it may be employed with a single barrel or with a plurality of barrels.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a double-barreled gun the combination of the barrels, a lock-frame hinged thereto, a depending lug on the barrels, provided with a notch in its rearward end, a plunger sliding in the frame for engaging the notch, a spring normally maintaining the plunger in its engaging, position, a trigger pivoted in the frame, a tail pivoted to the rearward end of the plunger, a friction-roller in the lower end of the tail, and a lug on the trigger for engaging the friction-roller to withdraw the plunger.

2. In a double-barreled gun the combination of the barrels, a lock-frame hinged thereto, a depending lug on the barrels, and provided with a notch in its rearward end, a spring-actuated plunger sliding in the frame and engaging the notch to maintain the barrels and the frame in alinement, a tail pivoted to the rear end of the plunger, and provided with a friction-roller in its lower end, and a trigger pivoted in the frame and means on the trigger for engaging the tail to withdraw the plunger.
